I'll just post this here as an "official" bug report also. When focusloop - attribute is set as true on a screen with a list (or with no focusable components), Kuix ends up in an endless loop looking for the focusable widget.
This can be easily reproduced by adding focusloop="true" - attribute to Kaprice's sl_s.xml - file and then creating a new list and opening that empty list in Kaprice. Will throw OutOfMemoryError
